Hi,
I've got a similar problem - I want to allow the customer to enter $ and
, in number fields.
validates_numericality_of fails if you start with a £ - fair enough.
validates_format_of doesn't seem to work - I think the value has been
converted to a number for this is checked and therefore it is too late.
before_validation seems the obvious answer.
Using the below code...
def before_validation
puts "#{self.price}"
self.price = self.price.to_s.gsub(/[^\d\.]/, "").to_i
puts "#{self.price}"
end
If I enter 999, then it correctly outputs 999 twice.
If I enter £999, then it outputs 0 twice - what!?
So I presume it has converted to a number before, my before_validation.
Anyone got aany suggestions?
I am really stunned that rails has such difficulty with something that
seems such a common problem - flexible user input.
Thanks,
James
